<p>In recent years, the urgent issue of how climate change affects food security has emerged as a significant concern. This paper highlights the complex interplay between food security and global climate change by examining the role of climate change in the food system, the interrelationship between food security and global climate change, and adaptation strategies to address these challenges. With a comprehensive analysis focused on China, this study systematically examines the complex dynamics linking food security and global climate change. The findings reveal important insights: (1) Global climate change is exacerbating insecurity in the food system and increasing its impact on Chinese food production; (2) Food demand emerges as the main driver of global climate change, while redistribution of food production factors exacerbates the climate crisis. (3) A synergistic and sustainable response can be achieved through a multi-pronged approach to addressing global climate change while ensuring food security and micro level, resilience. To effectively combat global climate change and ensure food security, this study highlights the critical importance of using micro-technologies for grain storage, prioritizing ecological building, pursuing a market-based approach at the macro level, and improving the food policy framework. In the context of global climate change, this study argues for a paradigm shift in food security research and a transition from a singular disciplinary, dimensional, and resource-centered approach to a multidisciplinary, multifactorial, and systematic integration of research. This transformative approach aims to promote a low-carbon and efficient food system that’s resilient to the challenges of global climate change.</p>
